NONSKID DEVICE.

Application filed. March 13, 1922-.

' T 0 all whom it may concern:

larl'y to nonskid devices which are formed withtwo'side vstrands and a plurality of cross strands. According to theusual construction of these devices the length of the side strands is but slightly in excess of the perimeter of the band or ring which the strands form whenthe nonskid device is in position on a tire and the spacing ofthe cross strands is suchthatthere is always at least one cross strand between the tire and 'the ground. With, these constructions it is not possible to attach the device to an automobile tire unless the nonski'd device is first placed on the ground and the tire is moved into position over it, or unless the tire is raised from the ground An object of this invention is to provide a nons'kid device which maybe attached to a tire in the customarymanner and which, in addition, may be quickly attached to anautomobile tire in a temporary manner when conditions are met which render it undesirable or impossible to jack up the tire or to move the automobile. A further object is to provide a device of the type stated which after having been temporarily attachedto a tire may be readily attached in the normal manner after the tire has been moved. A further object 'is to provide a nonskid device which while similar in generalconstruction to the present devices of this type has certain of the parts so designed that the device maybe readily applied to a tire in a temporary manner when it is not practical to apply it in the normal manner. A further object ofthe invention is to provide a nonskid device which will attain the object last stated and in which the parts which permit the attachment of the device in an emer gency or temporary manner do not interfere -with the normal operation; of the devicewhen it'is applied in the usual manner.

More specifically, an object of the invention is to provide a nonskid device in which certain o f the cross strands may be used to form temporary extensions of the slde spring 9 which is mounted on the Serial No. 543,387.

strands, or alternatively, these cross strands may be used to attach the device to the tire by fastening the separate ends of the device to the felly of the wheel.

An embodiment of my invention which Wlll attain these objects is illustrated in the accompanying drawings, in which ig. '1 is a fragmentary plan of the device and showing the two ends thereof in juXtaposltlon, but not connected;

Fig. 2 1s an elevation of the lower portion of an automobile wheel and tire and showals l, 2 and each of these strands is provided,

at one end thereof with a connecting element or fastener which is adapted to engage the other end of the respective strand when.

the nonskid device is applied to a tire.

These connecting elements or fasteners 3, 4

are locateda t the oppositely disposed ends of thetwo side strands 1, 2, respectively, thus providing one connecting element at each end of the device. The particular form of the connecting member forms no part of my invention but I have found that the formillustrated is well adapted for use with nonskid devices embodying my invention. These connecting elements or fasten ers'iwhich are designated generally by the numerals 3, a are identical in construction and asbest shown in Figs'l and 2, the fastener 4 consists in a link 5 which is at 'tached to the end of the side strand 2 and a lever pivoted on the linln This lever has a hook end 6 which cooperates with the link 5 to form a fastening device and an opposite or keeper end 7 which has all-portion or book 8 at the end thereof, the opening of the hook 8 being normally closedby the leaf portion 7 of the lever. V p

The cross strands which are located at the opopsite ends of thedevice', and which for convenience willbe designated as the terminal cross strands, are not permanently attached. at both ends to the side strands 1, 2 as are the other or intermediate cross strands 10, but have onlyione end perms nently attached to the side strands. These terminal cross strands 11, 12 have one end attached, respectively, to the side strands 1, 2 at or near the ends thereof which are opposite the connecting element ends. The free end of each of the terminal cross strands 11, 12 is provided with means for detachably securing the. same to the side strands 2, 1. respectively, and in the preferred construction this means consists in links or rings, 13. i i, respectively, through which the connecting element end of the appropriate side strandmay be passed.

lVhen the device is to beapplied to atire in the normal manner the free ends of the terminal cross strands areconnectedtothe side strands by passing the. tastenersB, 4'. through thelinlrs or. rings Id, 13,- respectively, as shown in Fig. 1. The device isthen applied to the tire in the. usual manner.

Under certain conditions, howeverv it may. be undesirable or impossible to jack up the.

wheels or to move them onto chains which have. been placed on the ground, as wou d be the case if thefvehiclewere standing or stalled in rutson soft ground. The device may then be attached to the tire. as shown-in Fig. 2. The terminalcross.strands are used to form temporary extensionsof the side strands by slipping the, rings 13, Mott of the sidestrandsQ. l, respectively, whereupon thestrands- 11. 1.2 be swung. over as shown by the dottedlines in lito. term extensions of theside. strands 1, 2, respectively. The centerportion of the device is. then'placed upon the top of-fithetire and the ends maybe joined as shown in Fig. 2 by engagin the rings 13, lt with the connectinzelements 3, 4, respectively. The device when applied in this way will afford suflicient traction to movethe car until it is out of difficulty and the device may. then .be secured to the tire in the normal manner.

In some cases, as when the tire is badly mired, the device maybe attached shown 14 with the connecting elements-4,3. respectively. In this manner theseparate endsof the nonskiddevice are each connected to the wheel and the car can then be moved suiiiciently to allow the application of the ,device in the normal manner.

Nonskiddevices of this general type are customarily formed of chain links and are commonly known as"--tire chains. While the embodiment which I have illustrated is constructed oat-chain links it-is to be under,-

stood that thevarious strands which make up the: devicemay be; formed of chain or posed ends of other suitable metal members, of flexible cables or of such other material as may be suited for the construction of devices of this character. While the embodiment which is herein described is the preferred form of my invention it is to be understood that the invention is not limited thereto since various changes may be madein the several parts of the device. such tor example, as the substitution of other forms of connecters for the elements 3, at, 13 and 14, and that these and other changes in the various parts their shape, size. and relative. location may be made without departing from the spiritot my invention as set forth in the following claims. I
